Bug Type: COM related
Operating System: Win XP Pro
PHP Version: 5.1.1
Assigned To: wez
New Comment:
Commenting out the line
$window->myclass = null;
in the supplied testcase means that the associated
"com_dotnet_dispatch_wrapper" resource is not destroyed
until we destroy any remaining resources in the regular
resource list during request shutdown when zend_deactivate()
calls zend_destroy_rsrc_list(). Unfortunately the dtor for
this COM resource references the object store which has
itself already been destroyed earlier in request shutdown
by zend_objects_store_destroy(). Changing the order of
object and resource shutdown might appear to be the easy
fix but I am sure this will lead to the reverse problem of
objects referring to resources when resource has already
been destroyed. As the references to the object store are
only required in order to add detail into some COM trace
entries then simply avoiding the reference when in request shutdown may
be the best/simplest approach in this case.
I will post a fix to Internals once I have something I am happy with.

Description:
------------
If IE is left open when a PHP script ends, and we have affixed a class
instance to IE, CLI generates an error.
Csaba Gabor from Vienna
Reproduce code:
---------------
<?php
$ie = new COM("InternetExplorer.Application"); // new IE
$ie->visible = true; // show it
$ie->Navigate2("about:blank"); // give IE empty DOM
while ($ie->readyState<4) usleep(10000); // wait for ready
class frob { } // dummy class
$frob = new frob; // instantiate it
$window=$ie->document->parentWindow; // window ref
$window->execScript("window.myclass=false"); // always allocate ie
vars
$window->myclass = $frob; // pathway to PHP
$window->alert ("Program is ending"); // proof of no errors to here
//$window->myclass = null; // CLI errors if this commented out
?>
Expected result:
----------------
PHP is quite good about cleaning up after itself. I expect PHP to
nicely finish and leave IE up, without and CLI error dialogs asking if
I want to send a report to Microsoft.
Actual result:
--------------
After dismissing the "Program is ending" alert box, I get the dreaded
CLI error dialog asking if I want to send a report to Microsoft.
